WalrusDirectClient class

Wallet-integrated Walrus client.

Usage (one-shot upload with upload relay):

final client = WalrusDirectClient(
  network: WalrusNetwork.testnet,
  suiClient: SuiClient(SuiUrls.testnet),
  walrusPackageId: '<package-id>',
  uploadRelay: UploadRelayConfig(
    host: 'https://upload-relay.testnet.walrus.space',
  ),
);

final result = await client.writeBlob(
  blob: rawData,
  metadata: preComputedMetadata,
  epochs: 3,
  signer: myAccount,
  deletable: true,
);

Usage (direct mode, no relay):

final client = WalrusDirectClient(
  network: WalrusNetwork.testnet,
  suiClient: SuiClient(SuiUrls.testnet),
  walrusPackageId: '<package-id>',
  encoder: WalrusBlobEncoder(),
);
client.setCommittee(committeeInfo);

final result = await client.writeBlob(
  blob: rawData,
  epochs: 3,
  signer: myAccount,
  deletable: true,
);

Usage (multi-step flow for dApp wallet):

final flow = client.writeBlobFlow(
  blob: rawData,
  metadata: preComputedMetadata,
);

await flow.encode();
final registerTx = flow.register(...);
// Sign registerTx with dApp wallet
await flow.upload(WriteBlobFlowUploadOptions(digest: txDigest));
final certifyTx = flow.certify();
// Sign certifyTx with dApp wallet
final result = await flow.getBlob();
